So hearing Alstrid make this mistake, and knowing that
a) Lincoln has a very important question from alt-Lincoln that he wants answered
b) he would have gone to Alstrid with Lincoln's question "who knew, who else knew about the transport
So that was my theory-- its Alstrid asking Alt-Broyles, but using a phrase of Lincoln's. When people paraphrase others, they don't necessarily adjust the language to reflect their understanding-- they may just use the language they're quoting.
Haven't seen 4.18 yet, so in your timeline, I may already be wrong!
